      Description

      We noticed the following error in the logs in the handling of a DescribeGroup request:
      ```
      org.apache.kafka.common.errors.UnsupportedVersionException: Attempted to write a non-default groupInstanceId at version 3
      ```
      The problem is that the field is not marked as ignorable. So if the user is relying on static membership and uses an older AdminClient, they will see this error.
